FLUSH SASH: Changing the game with Modus windows and doors

For many years uPVC windows and doors have been fairly limited when it comes to options. However, more recently the market has changed and people are breaking the mould and using windows and doors to make their home stand out from the crowd. Window and door manufacturers are now offering more and more options to put the power into the hands of the consumer.

The Modus range that we supply not only changes the game aesthetically but it also offers excellent security and performance benefits.

The six-chamber profile design makes frames stronger and the reinforcing used protects against forced entry. These chambers also enable Modus to achieve U-values as low as 0.7.

Let’s take a look at the different styles available.


With the aesthetics of traditional timber windows and all the benefits of uPVC windows, such as excellent energy efficiency and no risk of splitting or rotting, flush sash windows are flying off the shelves this year. Modus flush sash casements offer internally and externally flush sashes unlike other flush sash systems on the market.


Modus slim rebate sash windows offer internally flush and externally slim rebated sashes for a sleek look to rival aluminium systems. A range of grey and metallic finishes add to the aesthetic. This system delivers significant cost saving and enhanced thermal performance over that of aluminium.


Featuring slimmer sight lines than other systems, Modus standard sash is yet another option offering you something different that stands out from the norm. You can customise your style, colour and add options such as georgian bar to completely personalise your windows and doors.


Modus windows are available in a wide range of smooth colours and realistic woodgrain finishes. Options for colour both sides and colour on white are available. There are even premium woodgrain finishes available to provide an extra touch of class!


Modus windows are high-performance and low maintenance. There will be no repainting and there is very little maintenance that will need to be done to your windows and doors.

Modus contains 50% post-consumer recycled uPVC as standard. However, the outer faces remain virgin uPVC for colour matching at maintaining a quality finish.
